Abstract

In order to operate a plurality of utilities, the utilities are interconnected via a communication path. Each utility has a control device for controlling the utility and a memory for storing information factors which are used by the corresponding control device. The information factors corresponding to all the utilities are investigated by an extraction device to determine which are common to the utilities and which are related. Where the common information factors are identified, they are passed by the communication path to the memories of all the utilities. Similarly, when related information factors are found, a calculating device calculates common information which is also passed via the communication path to the memories of all the utilities. In this way, the utilities may operate more efficiently than when they are operated on a stand-alone basis. The investigation of the information factors, and the calculating of common information from related information factors may be distributed among the utilities or carried out by a common control device. The utilities may be electric power supply systems, district heating and cooling systems, sewage disposal systems, waste recovery systems, etc.

Claims

1. A method of operating a plurality of different types of utilities in a geographical region, each of said plurality of utilities having control means for controlling the physical structure of the corresponding utility in response to a plurality of information factors related to the operation of the corresponding utility, each of said plurality of utilities determining the behavior of a different physical system of said geographical region;

wherein said method comprises the steps of;

identifying at least one first information factor of said control means of one of said plurality of utilities which is related to at least one second information factor of said control means of another of said plurality of utilities;

deriving common information from said at least one first information factor of said control means of said one of said plurality of utilities and said at least one second information factor of said control means of said another of said plurality of utilities;

supplying said common information to said control means in each of said plurality of utilities; and

operating each of said plurality of utilities such that the corresponding control means uses said plurality of information factors and said common information in the control of the physical structure of the respective utility.

2. A method according to claim 1, wherein said first and second information factors are the same and correspond to said common information factor.

3. A method according to claim 1, wherein said first and second information factors are related, and said deriving of said common information comprises calculating said common information factor from said first and second information factors.

4. A method according to claim 1, wherein said identifying and deriving steps are carried out in one of said control means of said plurality of utilities.

5. A method according to claim 1, wherein said identifying and deriving steps are carried out in a common control device connected to said control means of each of said plurality of utilities.

6. A method according to claim 1, wherein said one of said plurality of utilities is an electricity supply system, said another of said utilities is a district heating and cooling system, and said step of deriving said common information deriving power dissipated.

7. A method according to claim 1, wherein said one of said plurality of utilities is a sewage disposal system, said another of said utilities is a waste disposal system, and said step of deriving common information deriving the amount of waste produced in the geographical region.

8. A method according to claim 1, wherein said one of said plurality of utilities is a surface water management system, said another of said utilities is a building management system and said step of deriving common information identifying air temperature.

9. A method according to claim 1, wherein said one of said plurality of utilities is a vehicle management system, said another of said utilities is a power generating system, and said step of deriving common information includes deriving pollution information.

10. A method according to claim 1, wherein said one of said plurality of utilities is a vehicle management system, said another of said utilities is a district heating and cooling system, and said step of deriving common information includes deriving pollution information determining the behavior of a different physical system of said geographical region.

11. A utilities network system comprising a plurality of different types of utilities in a geographical region, each of said plurality of utilities having control means for controlling the physical structure of the corresponding utility in response to a plurality of information factors related to the operation of the corresponding utility, each of said plurality of utilities including means for determining the behavior of a different physical system of said geographical region;

wherein said system further includes;

identification means for identifying at least one first information factor of said control means of one of said plurality of utilities which is related to at least one second information factor of said control means of another of said plurality of utilities;

deriving means for deriving common information from said at least one first information factor of said control means of said one of said plurality of utilities and said at least one second information factor of said control means of said another of said plurality of utilities; and

supply means for supplying said common information to said control means in each of said plurality of utilities;

said control means of each of said plurality of utilities operating to control the physical structure of the corresponding utility on the basis of said plurality of information factors and said common information.

12. A utilities network system according to claim 11, wherein said identification means, said deriving means and said supply means form part of one of said control means of said plurality of utilities.

13. A utilities network system according to claim 11, having a common control device, said common control device including said identification means, said deriving means, and said supply means.

14. A utilities network system according to claim 11, wherein said one of said plurality of utilities is an electricity supply system, and said another of said plurality of utilities is a district heating and cooling system.

15. A utilities network system according to claim 11, wherein said one of said plurality of utilities is a sewage disposal system, and said another of said plurality of utilities is a waste disposal system.

16. A utilities network system according to claim 11, wherein said one of said plurality of utilities is a surface water management system, and said another of said plurality of utilities is a building management system.

17. A utilities network system according to claim 11, wherein said one of said plurality of utilities is a vehicle management system, said another of said plurality of utilities is a power generating system.

18. A utilities network system according to claim 11, wherein said one of said plurality of utilities is a vehicle management system and said another of said plurality of utilities is a district heating and cooling system.

19. A control device for controlling the physical structure of a utility in a utilities network system, having a plurality of utilities for supplying respective services, said control device comprises:

identification means for identifying at least one first information factor of a first one of said plurality of utilities which is related to at least one second information factor of a second one of said plurality of utilities, each information factor being related to the operation of a utility;

derivation means for deriving common information from said at least one first information factor; and

supply means for supplying said common information to each of said plurality of utilities for use in controlling the physical structure thereof.
